Calculate the speed in m/s at which Earth revolves around the sun. Note: The orbit is nearly circular.
Speed of revolution of Earth around the Sun in m/s.
Answer to Problem 40A
Explanation of Solution
Given:
Assume orbit of Earth nearly circular.
Formula Used:
The speed is given as,
Where,
Calculation:
The time taken by Earth to revolve around the sun is 365 days.
So,
Now, distance of earth from the sun is around
So, distance travelled by earth in one revolution
So, the speed of Earth in its orbit is
Conclusion:
Therefore, the speed of revolution of Earth around the sun is
